Description

[Detailed description of the invention] The present invention relates to a fire extinguishing system equipped with a so-called portable fire extinguisher.The purpose of the invention is to allow the fire extinguisher to be carried and used at a desired fire scene, and to prevent the fire extinguisher from being used in the event of a fire. To provide a fire extinguishing device in which a valve automatically opens and extinguishing liquid can be extinguished by injecting extinguishing liquid from a nozzle set in advance toward a desired extinguishing target.

The illustrated example of actual tM will be described below.

Reference numeral 1 denotes a portable fire extinguisher, in which a suitable fire extinguishing liquid is pressurized and stored with carbon dioxide gas in a cylindrical tank 2, and a nozzle 4 is attached to the opening of the tank 2 via a valve 3.

Reference numeral 5 denotes a grip member attached to the opening of the tank 2, and the base end of a lever 6 is rotatably pivoted to the base end (right end in FIG. 1) of the grip member 5.

The lever 6 is in the closed position (where the valve 3 is closed).
(Fig. 1) and an open position (Fig. 2), and is biased to maintain the closed position by a spring (not shown) mounted between it and the gripping member 5.

Thus, in the fire extinguisher 1, the valve 3 opens by rotating the lever 6 against the bias of the spring and displacing it to the open position.
Fire extinguishing liquid is injected from the nozzle 4.

The fire extinguisher 1 is removably mounted on a support stand 8 installed on the floor T of the kitchen by wrapping a band 9 attached to the support stand 8 around the tank 2. An upper plate 11 suspended horizontally from the upper end of a side plate 10 provided on the side covers the upper part of the lever 6 to protect the lever 6 from rotating to the open position due to an accidental collision with an object.

Reference numeral 12 denotes a drive unit provided between the side plate 10 of the support base 8 and the fire extinguisher 1, which is connected to the upper end of the upper rod 14 of the rods 14 and 15 having a turnbuckle 13 in the center and the cap 16 at the upper end. The lower end of link 1T is pivotally connected to A spring stopper 20 is attached.

Reference numeral 21 denotes a spring retaining ring screwed into the upper end opening of the receiver cylinder 18, into which the lower rod 15 is loosely inserted.

The drive body 12 is removably connected to the lever 6 by fitting a cap 16 to the tip of the lever 6, and its length is adjusted by a turnbuckle 13 so that the lever 6 is in the closed position. When the spring stopper 20 is in contact with the lower end opening of the receiving tube 18 and the coil spring 19 is compressed within the receiving tube, a downward force is applied, and this urging force causes the drive body 12 to descend. This causes the lever 6 to rotate and move from the closed position to the open position.

Therefore, the drive body 12 is connected to the fire extinguisher 1 at the turnbuckle 13.
The length of the lever 6 can be adjusted according to the height of the lever 6, and the driving force can be applied to the lever 6 by moving the spring stopper ring 21 up and down to change the distance between the lever 6 and the spring stopper 20 and adjust the repulsive force of the coil spring 19. It can be made to correspond to the grip strength.

22 is a locking mechanism provided on the lower side of the receiving tube 18 of the support base 8;
That is, a guide tube 24 with a guide groove 23 formed around it is vertically suspended between the lower bottom plates 25 and 26 on the support base 8, and a sliding ring 28 with a retaining piece 27 protruding from the guide tube 24 is placed around the guide tube 24. One side of an L-shaped sliding rod 29 is fitted in the guide groove 23 so as to be vertically movable and horizontally rotatable below the sliding ring 28. , and the other side protrudes outward from the guide groove 23.

The other side of the sliding rod 29 is fitted into the locking step 30 formed in the upper part of the guide groove 23, and the engaging piece 27 of the sliding ring 28 is brought into contact with the locking step 30 formed in the upper part of the guide groove 23. By engaging with the lower surface of the spring stopper 20 that is in contact with the lower end opening of the cylinder 18,
The drive body 12 can be locked in a state where the lever 6 is maintained in the closed position against the bias of the coil spring 19.

Further, when the sliding rod 29 is rotated in a required direction and the other side is removed from the locking step 30, the drive body 12 is released from the lock and lowered by the biasing force of the coil spring 19, and As a result, the sliding ring 28 and the sliding rod 29 are also lowered, and the lever 6 is displaced from the closed position to the open position.

31 is a solenoid, which is attached to the top of the support base 8 and the bottom bottom plate 2.
5.26, the base end of the locking piece 34 is rotatably mounted on a mounting plate 33 which is horizontally mounted on the right side of the locking mechanism 22 (FIGS. 1 and 2) and provided at the tip of the drive shaft 32. This latching piece 34 is pivotally attached.
The hook-shaped portion at the tip of the slide rod 29 is hooked onto the other side of the sliding rod 29 that is fitted into the locking step 30, and is biased by a spring (not shown) to maintain this state. ing.

Then, when the solenoid 31 is activated and the drive shaft 32 is displaced to the right (Figs. 1 and 2), the latch piece 34 is attached to the sliding rod 29.
is horizontally rotated in a required direction, and the other side portion is disengaged from the locking stepped portion 30, thereby releasing the locking of the drive unit body 12.

35 is a controller installed at a predetermined position in the building, and it is an automatic fire detector 3 installed on the ceiling above the gas range 36.
7. A manual switch 38 mounted on the required wall surface, an alarm buzzer 39, the solenoid 31, etc. are connected (FIG. 3).

When the automatic fire detector 37 and manual switch 38 are activated, the alarm buzzer 39 sounds, the solenoid 31 is activated, the drive body 12 is lowered by the bias of the coil spring 19, and the lever 6 is moved to the open position. It is set to be displaced.

40 is an injection head provided above the gas range 36, and the base end of a hose 41 having the injection head 40 attached to its tip is detachably connected to the nozzle 4 of the fire extinguisher 1.

Note that the nozzle 4 may be directed directly toward the gas range 36.

However, if a fire breaks out from the gas range 36 and the automatic fire detector 37 detects it or the manual switch 38 is activated, the alarm buzzer 39 will sound and the solenoid 31 will be activated to open the lever 6. position, the valve 3 opens, and the extinguishing liquid is supplied from the nozzle 4 to the injection head 40 via the hose 41 and is injected toward the gas range 36.

In addition, a fire broke out in a place other than the gas range 36, and the fire extinguisher 1
When the user wants to carry the device, the user can remove the band 9, remove the cap 16 to disconnect the lever 6 and the drive body 12, and remove the nozzle 4 from the hose 41 to carry it to a desired location.

As is clear from the above, according to the present invention,
A cap is fitted onto the lever of a portable fire extinguisher, and the drive body is detachably connected to the lever, and when an automatic fire detector detects a fire, the drive body is driven, the lever is operated, and the valve is opened. Since extinguishing liquid is sprayed from a nozzle that is set in advance in the direction of a predetermined fire extinguishing target, it is possible to automatically extinguish a fire that occurs in a predetermined location, and also prevent a fire from occurring in a location other than the above predetermined location. In such cases, the fire can be extinguished by disengaging the driving body and the lever and carrying it to a desired location.

The driving force of the driving body is adjusted to correspond to the predetermined gripping force of the lever by adjusting the biasing force of the spring, and the length of the driving body is adjusted to a length corresponding to the height of the fire extinguisher using a turnbuckle. This makes it possible to use existing portable fire extinguishers with different heights and lever gripping forces as appropriate, making it highly versatile and eliminating the need for a dedicated device for each specific fire extinguisher. Economical.
